TAGRISSO (osimertinib) Tablet

AstraZeneca Pharmaceuticals, Wilmington, DE, USA

INDICATION: Treatment of patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC), as detected by an FDA-approved test, whose disease has progressed on or after EGFR tyrosine kinase inhibitor (TKI) therapy.

REG PATHWAY: sNDA

  • Accelerated NDA approval in November 2015 for this indication
  • Fast Track, Breakthrough Therapy Designation, Orphan Drug Designation for  treatment of EGFR mutation-positive NSCLC

EFFICACY:

  • Single randomized, multicenter open-label, patients with metastatic EGFR T790M mutation-positive NSCLC (identified by the cobas® EGFR mutation test), n=279, TAGRISSO vs.  platinum-based doublet chemotherapy  until intolerance to therapy, disease progression, or investigator determination of no benefit
  • Major efficacy outcome measure: Progression-free survival (PFS) per RECIST v1.1; Other- Objective Response Rate (ORR), Duration of Response (DOR)
  • Median PFS in months (95% CI):  10.1 (8.3, 12.3) vs. 4.4 (4.2, 5.6), p<0.001
  • Confirmed ORR: 65% (95% CI: 59%, 70%) vs. 29% (95% CI: 21%, 37%)
  • Median DOR:  11 months (95% CI: 8.6, 12.6) vs. 4.2 months (95% CI: 3.9, 5.9)
  • Confirmed CNS ORR: 57% (95% CI: 37%, 75%) vs. 25% (95% CI: 7%, 52%)

SAFETY:

  • Most serious adverse reactions: Interstitial lung disease/pneumonitis, QTc interval prolongation, cardiomyopathy, keratitis
  • Most common adverse reactions: Diarrhea, rash, dry skin, nail toxicity, and fatigue

AUSTEDO (deutetrabenazine) tablets

Teva Pharmaceuticals, North Wales, PA, USA

INDICATION: Treatment of chorea associated with Huntington’s disease

REG PATHWAY: NDA, Orphan Drug Designation

  • First approval of deuterated drug

MECHANISM OF ACTION: Major circulating metabolites  are reversible inhibitors of a vesicular monoamine transporter 2(VMAT2), resulting in decreased uptake of monoamines into synaptic vesicles and depletion of monoamine stores.

EFFICACY:

  • Single randomized, double-blind, multi-center trial, ambulatory patients with manifest chorea associated with Huntington’s disease, n=90, AUSTEDO vs placebo for 12 weeks
  • Primary efficacy endpoint: Total Maximal Chorea Score, an item of the Unified Huntington’s Disease Rating Scale (UHDRS)
  • Score Improvement: 4.4 units vs. 1.9 units (p<0.0001); at Week 13 follow-up visit (1 week after discontinuation of the study medication), Scores of patients who had received AUSTEDO returned to baseline

SAFETY:

  • Boxed Warning: Depression and Suicidality
  • Adverse Reactions: Neuroleptic Malignant Syndrome,  Akathisia, Agitation, and Restlessness, Parkinsonism, Sedation and Somnolence, QTc Prolongation, Hyperprolactinemia, Binding to Melanin-Containing Tissues

IPSOGEN JAK2 RGQ PCR Kit

Qiagen, Manchester, UK

INDICATION FOR USE:

For qualitative in vitro diagnostic test for the detection of the JAK2 V617F/G1849T allele in genomic DNA extracted from EDTA whole blood. The ipsogen JAK2 RGQ PCR Kit is a real time PCR test performed on the QIAGEN Rotor-Gene Q MDx instrument.

The test is intended for use as an adjunct to evaluation of suspected Polycythemia Vera, in conjunction with other clinicopathological factors.

This test does not detect less common mutations associated with Polycythemia Vera including mutations in exon 12 and is not intended for stand-alone diagnosis of Polycythemia Vera

REG PATHWAY: De Novo Request

  • Regulation Number: 21 CFR 866.6070
  • Regulation Name: Mutation detection test for myeloproliferative neoplasms
  • Regulatory Classification: Class II
  • Product Code: PSU

GENERIC DEVICE TYPE: Mutation detection test for myeloproliferative neoplasms

In vitro diagnostic device intended for the detection of the JAK2 V617F/G1849T allele in genomic DNA extracted from whole blood. The test is intended for use as an adjunct to evaluation of suspected Polycythemia Vera, in conjunction with other clinicopathological factors.

RISKS & MITIGATIONS:

  • False Negative and False Positive Results; Special Controls
